Abstract
A wearable fluid delivery system comprising a single-use device with a tube, a pump, and a nutrition container with a fluid. The system further includes a module including a processor, a battery, and an electric motor with an output member. The processor is configured to operate the electric motor. The single-use device is releasably coupled to the module such that the output member is coupled to the pump when the single-use device is coupled to the module, and the output member drives the pump to cause the fluid to travel through the tube.
Core Innovation
The invention provides a wearable enteral-fluid delivery system in which an assembly including a tube, a pump, and a container defining a cavity configured to hold a fluid is releasably coupled to a module. The module includes a processor, a battery, and an electric motor with an output member, and the processor operates the electric motor to drive the pump when the assembly is coupled to the module. The output member is configured to couple to the pump when the assembly is coupled to the module so that the output member drives the pump to propel fluid through the tube toward a patient access port.
The invention includes a module having an optical sensor having a recess, where the tube is at least partially positioned within the recess and the housing of the pump at least partially covers the optical sensor. The invention also addresses coupling-related safety behavior through coupling detection so that the motor drive behavior is conditioned on whether the assembly is coupled to the module. Further refinements include gravity-independent complete expulsion through embedded channel structures in the nutrition container that define fluid flow paths.
The invention further provides mechanical and identification features for compatibility and verification. The pump architecture includes planet gears arranged within a pump housing so that at least one planet gear directly contacts the tube. The system further includes machine-readable and wireless identification, such as RFID/QR/NFC or barcode, for fluid/pump compatibility or verification, and includes corresponding reader/sensor detection features. Mechanical interfaces using recesses/detents and features to support optical sensing without ambient interference are also described.
Claims Coverage
The partial document contains two independent claims, each directed to a wearable fluid delivery system architecture with a releasably coupled pump assembly and drive module. Claim 1 centers on an optical sensor recess arrangement integrated with the tube and pump housing, while Claim 19 centers on the container cavity being formed by wall panels and an extending channel.
Releasably coupled pump assembly to motor module
An assembly including a tube, a pump, and a container defining a cavity configured to hold a fluid is releasably coupled to a module including a processor, a battery, and an electric motor with an output member, wherein the assembly is coupled such that the output member is coupled to the pump and the output member drives the pump.
Optical sensor recess with tube positioned within and pump housing covering
The module includes an optical sensor having a recess, wherein the tube is at least partially positioned within the recess, and wherein a housing of the pump at least partially covers the optical sensor.
Container cavity at least partially formed by first wall panel, second wall panel, and channel
The container includes a first wall panel and a second wall panel coupled to the first wall panel, and wherein the first wall panel includes a channel that extends away from the second wall panel, wherein the cavity is at least partially formed by the first wall panel, the second wall panel, and the channel.
Across the two independent claims, the core coverage is a releasably coupled system where a module having a processor and motor output drives a pump in an assembly containing a tube and a fluid-holding cavity. Claim 1 further requires an optical sensor recess in the module with the tube positioned in the recess and the pump housing covering the optical sensor, while Claim 19 further requires the container cavity to be at least partially formed by wall panels and an extending channel.
